    • PURPOSE: A high efficiency refrigeration system is provided which utilizes one or more vortex generators and a diffuser to increase the overall efficiency of a refrigeration system. CONSTITUTION: A refrigeration system includes a compressor(12), a condenser(14), an expansion device(16) and an evaporator(18). The various components are connected together via a conduit(19). A refrigeration system is a closed loop system that continuously circulates a refrigerant through the various elements. The refrigerant is a condensible vapor. Some common types of refrigerant include R-12, R-22, R-134A, R-410A, ammonia, carbon dioxide and natural gas. The main steps in the refrigeration cycle are compression of the refrigerant by the compressor(12), heat rejection of the refrigerant in the condenser(14), throttling of the refrigerant in the expansion device(16), and heat absorption of the refrigerant in the evaporator(18). As indicated previously, this process is referred to as the vapor compression refrigeration cycle. The efficiency of a refrigeration cycle(and by analogy a heat pump cycle) depends primarily on the heat absorption from the evaporator(18) and the efficiency of the compressor(12). The former depends on the percentage of liquid in the liquid-vapor refrigerant mixture before the evaporator, whereas the latter depends on the magnitude of the pressure differential across the compressor.
    • 目的:提供一种高效率的制冷系统,其利用一个或多个涡流发生器和扩散器来提高制冷系统的整体效率。 构成:制冷系统包括压缩机(12),冷凝器(14),膨胀装置(16)和蒸发器(18)。 各种部件通过导管(19)连接在一起。 制冷系统是使制冷剂连续循环通过各种元件的闭环系统。 制冷剂是可冷凝的蒸汽。 一些常见的制冷剂类型包括R-12,R-22,R-134A,R-410A,氨,二氧化碳和天然气。 制冷循环中的主要步骤是压缩机(12)对制冷剂的压缩,冷凝器(14)中的制冷剂的排热,膨胀装置(16)中的制冷剂的节流以及制冷剂的吸热 蒸发器(18)。 如前所述,该方法被称为蒸气压缩制冷循环。 制冷循环的效率(类似于热泵循环)主要取决于蒸发器(18)的吸热和压缩机(12)的效率。 前者取决于蒸发器前液体 - 蒸汽制冷剂混合物中液体的百分比,而后者则取决于压缩机两端的压差大小。
